Oil-coated scrap metal material such as turnings or borings is fed in through openings 42 on to the stationary hearth 44 of a furnace 14 where it is heated before being discharged, free of oil, through an outlet 46 from whence it is passed directly to a briquetting machine (18, Fig. 1). The oil serves as fuel for the furnace ; combustion air enters the furnace through the openings 42 along with the material to be heated. The material is moved over the surface of the hearth towards the outlet 46 by a rotary rake system having aims 50 extending outwardly from an air cooled shaft 52 and carrying blades 54. The combustion gases exit through  an outlet 40 which communicates with an afterburner 28 serving to reduce or eliminate the presence of unburned oil vapour in the exhaust gases; the exhaust gases are then passed through a scrubber (26, Fig. 1) before being exhausted through a stack (32)-into the atmosphere. The furnace may include a burner to provide initial combustion on furnace start up.  The furnace may also be used to treat other materials which carry combustible substances, such as pieces of ore having fuel associated therewith.

In an apparatus for the distillation of liquid, e.g. sea water, a stream of the water flows into a chamber 50 at reduced pressure where dissolved gases (air) are released from the water, the degasified water then flows through an evaporation unit 52 where part of the water evaporates under reduced pressure, the vapours being conducted into a condensation chamber 68 for desalinated water which is collected in receiver 72, the non-evaporated water leaving unit 52 flows as a high-velocity stream down barometric leg 54 to the sea, and the gases released in chamber 50 are drawn via conduit 74 into this high velocity stream. In unit 52, the water may flow down the sides of vertical plates. The sea water to be treated is pumped through conduit 40 and the tubes 43 of the condenser into a heater 46, and the stream of heated water flows through valve 48 into chamber 50. The heater 46 may be the condenser of a stream power plant. A certain amount of the dissolved gases are only released from the water near the bottom of unit 52, these gases flow with steam into condensation chamber 68, from which the gases are pumped through conduit 78 into barometric leg 54.

Abstract: 1446679 Substation apparatus; pulse circuits NORTHERN ELECTRIC CO Ltd 5 Dec 1974 [6 Dec 1973] 52662/74 Headings H4K and H3T In a push button data sender in which data to be transmitted can be set up in a storage means prior to transmission the data signals and a telephone handset are coupled to the line via a hybrid. As described the device may be used both as a data sender and a repeat dialler. All signals transmitted may be in multi-frequency form or the first digit train transmitted may be in impulse form (for dialling) with subsequent data transmission in multi-frequency form, an automatic sender arrangement for this mode being detailed in Fig. 5, not shown. The Figure shows a keypad 20 which provides markings in 1 out of 4 and 1 out of 3 form to a decoder 21 which applies the digits in binary form to a memory 22. The locations of the memory are repeatedly read by a display address generator and the contents of each location are read out (non-destructively) to a LED 8 bar code decoder 29. The code is applied via a driver 30 to the corresponding digit display identified by decoding at 31 the display address generator. The display appears to be continuously illuminated. If the correct number has been entered the # key is depressed causing the memory address generator to address the memory locations gating the digits to the sender. Writing into the memory is initiated in response to operation of the * key. An error correct key 35 is provided. One depression of this key deletes the last digit entered while a double depression clears the memory. An anti-contact-bounce circuit 34 comprises a two stage counter 340 which if it is allowed to count of 3 pulses from a clock 28, without being reset by NOR gate 345 by interrupts in a signal from a key 20 or 35, sets a bi-stable 342 until the key is released and provides a two millisecond output strobe pulse at 344, the duration of which is determined by the clock driving the counter to zero.
